The article was appeared in 《Green Chemistry》. They have made some progress in their research.Quality Control of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol The article mentions the following:
Metal-free CNTs exhibit high activity (conversion rate 99.6%, 6 h) towards the synthesis of chiral hydrobenzoin from benzaldehyde under near-UV light irradiation (320-400 nm). The CNT structure before and after the reaction, the interaction between the mol. and the CNT surface, the intermediate products, the substitution effect and the influence of light on the reaction were examined using various techniques. A photoexcited conduction electron transfer (PECET) mechanism for the photocatalytic reduction using CNTs was proposed. This finding provides a green photocatalytic route for the production of hydrobenzoin and highlights a potential photocatalytic application of CNTs. The experimental procedure involved many compounds, such as rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .
Desymmetrization of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas:579-43-1 Quality Control of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol) using chiral phosphine catalyst has been reported. Conversion of meso-hydrobenzoin to trans-stillbene oxide by treatment with an aryl sulfonyl chloride and aqueous sodium hydroxide has been reported.
